CARL AUGUST GREEN, OF KATRINEHOLM, SWEDEN.

SEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 684,424, dated October15, 1901. Application filed December 1, 1899. Serial No. 738,851. (Nomodel.)

.To all whom it 17m/y concern:

Be it known that I, CARL AUGUST GREEN, foreman, a subject of the King ofSweden and Norway, and a resident of Katrineholm, in the Kingdom ofSweden, have invented new and useful Improvements in Machines for Sowingin Rows and in Width, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to improvements in machines for seeding in rowsand in width.

The invention is illustrated in the accompanying drawings, in which-Figure l shows a cross-section of the seedbox, and Fig. 2, a view of thesame, partly in section. Fig. 3 is a plan view of a device forregulating the size of openings at the bottom of the seedbox, throughwhich openingsthe seedsdescend into the shares. Figs. 4 and 5 show amodification of this latter device. Fig. 6 is a transverse section ofthe hopper and seed-feeders, showing also furrow-openers and certainaccessory devices.

A shaft a, carrying rings b, is journaled in the bottom of the seedboXabove openings h, which communicate with the ducts n, leading to theshares, said rings being on their peripheries provided with a pluralityof radial pins o, which at the rotation of the rings transmitted fromthe wheels ot' the machine agitato and distribute the seed to theopenings h and cause the same to fall down to the shares. The device forregulating the size of the openings h, leading to the shares, consistsof two bars CZ and e, located side by side at the bottom of the seedboXand movable in their longitudinal direction, said bars being providedwith teeth or projections j' and g, so spaced as to leave recesses ofconsiderable longitudinal extent between the teeth of each individualbar, in which the teeth of the opposing bar play as the bars are movedin opposite directions,for min g between themselves the aforesaidoutlet-openings h. When the bars, and consequently the teeth orprojections, are, by means of a special arrangement, displaced in theone direction or the other, the openings are increased'ordecreased,there by regulating the quantity of seed fed to the shares.

Figs. 4 and 5 show a somewhat-modified arrangement of theregulating-bars, in which arrangement teeth or projections on one of thebars d extend into and fit in openings or recesses made in the other bare', the arrangement being such that the bars are movable toward and fromone another, so that the projections are moved inward or outward in therecesses, the size of the outlet-opening being thereby rincreased ordecreased. The two bars and the teeth of one and openings or recesses ofthe other, which projections and recesses, as in the former case, aresituated in the' same plane and in the same space of displacement,havefor their purpose to produce-in the latter case by the displacement ofthe teeth or projections inward and outward in the Vopenings or recessesand in the former case by the displacement of teeth or projections inthe longitudinal direction of the bars-variable outlet-openings in oneand the same plane.

On each of the regulating-bars d and e is a lug 7c, Fig. 3, which lugsare by means of pins Zconnected to lever i, which can turn on a pivot m,so that when the lever 1l is swung in the one direction or the othertheregulatingbars are mutally displaced, the openings between theprojections being thereby increased or decreased. In the arrangementshown in Figs. 4 and 5 the adjustment of the bars d' and e' in theirrelative positions can be executed, for instance, thereby. On a specialbar b are oblique projections a', formed at a suitable distance from oneanother, said projections moving in slots arranged in the seedboxobliquely to the longitudial direction of the bars and opposite theprojections. The bar b is located below and moves in a longitudinalgroove in one of said regulating-bars (see Fig. 5) in such a manner thatthe same when displaced in either direction actuates, by means of itsprojections, the bar provided with said groove, thereby causing this barto move in the desired direct-ion for adj ustment. The adjustment-bar bis connected 'to the lifting-lever k for raising the shares out Vof andfor lowering them into the ground, so that the regulating-openings areshut or opened, in the same time as the shares are raised or lowered.

The lever t' is swung by means of an arrangement connected to thelifting-lever R IOO shares S S. This arrangement consists of a sway-barp, provided with a longitudinal slot and at its one end with a tail o,enteringin a hole made in the lever t. The other end of the sway-bar pforms a bow surrounding a collar or shaft r, which is connected to theaforesaid lifting-lever for raising and lowering the shares. The collaror shaft r has a pin s, entering into an oblique groove or camslot q inthe bow in order to cause the arm p to swing when the shaft fr, andconsequently the pin s, is rotated. The sway-bar p is movable upon apivot t', which by means of a nut fu' or the like can be adjusted up anddown and held in any position in a vertical slot u, made in a plate t,fixed to the rear of the seedboX, thereby being moved up or down in thelongitudinal slotvin the sway-bar and changing the relative length ofits lever-arms. By means of this the tail-pin c at the lower end of thesway-bar is caused to move the levert' to the right or to the left,according to the position to which the pivot fu is shifted, and thusadjust the normal size of the apertures h according to the seed to besowed, this adjustment being so far independent of the action producedby the rocking of the shaft r when the shares are raised.

The lifting-lever R is directly att-ached to shaft 7', and the lattersupports, by outsetting arms r at suitable distances apart, a liftingbarR', connected by links r2 with the individual shares, so that when thelever R is raised along the locking-segment T shaft r will be rocked,the shares lifted, and the feed cut off whatever the adjustment ofthefeedopenings h, andwhen the shares are again depressed the feed-openingswill be restored to the original adjustment, due to the position ofpivot v. Thus the adjustment of the feed is made to depend upon thesway-bar and pivot through which the opening and closing are effected,the change in relative length of the lever-arms of the sway-bar in orderto eect the adjustment being proportionate to the swing necessary toeffect the perfect cutoff of the feed from that adjustment as the sharesare raised or restoration thereto as they are depressed.

I claiml. The combination with a seedbox and feed-ducts, of two parallelmovable bars having projections and recesses whereby feedapertures areformed, a series of shares with which the feed-ducts communicate, alever for lifting and depressing said shares, and intermediateconnections between said lever and said bars whereby the bars are movedto close the feed-apertures when the shares are raised and reversel ymoved to open said apertures when the shares are depressed.v

2.
